Charlie's Reply: No - they won't wear the laser significantly any more than leaving the light on in your room when you've stopped reading won't cause wear on your eyes.

Could it be a matter of "unorthodox" DVD types (DVD9, DVD2)?
Charlie's Reply: No. It's possibly air noise whistling through those "cracks" you mentioned.

Should I stop running these games in my PS 2?
Charlie's Reply: For what my opinion is worth, no - don't worry.
